Pennsylvania teachers heading out of state to find jobs. Hunting for a position as a first-grade teacher in Pennsylvania became a full-time job for Williams Township native Sarah Widmer. After Widmer graduated from Shippensburg University in 2012, she immediately began her job hunt, applying to every school district in Pennsylvania; all 500 of them.
By Definition. A single board foot of lumber measures 1 inch thick, 12 inches wide and 12 inches long. The formula for calculating board feet is first to multiply thickness by width by length -- in inches. Then divide the total by 144 for the total board footage of a given board.
The answer depends on the moisture content. An average weight of a board foot of Douglas-fir, which is not one specific tree but one of about a dozen different trees, is about 2.8 to 2.9 pounds per board foot. You could make a quick calculation based on that. And don't forget that a 2 x 4 is not really 2 by 4 in size.
